Users Guide

The number of consecutive packets that must be received from a BFD peer is 3.
The BFD role is active
Command Mode CONFIG
Usage Information
Use this command to enable or disable BFD for all the configured IPv4 static routes for the specified VRF. If you
do not specify a VRF name, the command is applicable for the default VRF.
The no version of this command disables BFD on a static route
Example
OS10(config)# ip route bfd interval 250 min_rx 250 multiplier 4 role active
Supported
releases
10.4.2E or later
ipv6 route bfd
Enables or disables BFD on IPv6 static routes.
Syntax
ipv6 route bfd [vrf vrf-name] [interval millisec min_rx min_rx multiplier role
{active | passive}]
Parameters
• vrf vrf-name — Enter the keyword VRF and then the name of the VRF to configure static route in that
VRF.
• interval milliseconds — Enter the time interval for sending control packets to BFD peers, from 100
to 1000.
• min_rx milliseconds — Enter the maximum waiting time for receiving control packets from BFD peers,
from 100 to 1000. Dell EMC recommends using more than 100 milliseconds.
• multiplier number — Enter the maximum number of consecutive packets that must not be received
from a BFD peer before the session state changes to Down, from 3 to 50.
• role {active | passive} — Enter active if the router initiates BFD sessions. Both BFD peers can
be active simultaneously. Enter
passive if the router does not initiate BFD sessions, and only responds to a
request from an active BFD to initialize a session.
Default
The time interval for sending control packets to BFD peers is 200 milliseconds.
The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds.
The number of consecutive packets that must be received from a BFD peer is 3.

show bfd neighbors
Displays information about BFD neighbors from all interfaces using the default VRF.
Syntax
show bfd neighbors [detail | interface]
Parameters
• detail — (Optional) View detailed information about BFD neighbors.
• active — (Optional) View information about the active BFD neighbors whose state is up.
• interface interface-type — (Optional) Enter one of the following interface types:
